The incident report said John E. Brennan's actions Tuesday evening caused some passengers to cover their eyes and their children's eyes while others looked, laughed and took photos. Two screening lanes were temporarily closed.

Police say the Portland man was arrested for investigation of indecent exposure and disorderly conduct.

The Oregonian reports the Port of Portland summary said Brennan "disrobed completely naked" while going through a security screening area.

He later told authorities he flies often and "disrobed as a form of protest against TSA (Transportation Security Administration) screeners he felt were harassing him."
